IMPROVEMENT IN GHANGEABLE STENGIL-PLATES.

TO AIiL WHOM IT MAY CONCERN:

Be itrknown that I, JAMES J. DE' BARRY, of the city of Brooklyn, county of Kings, and State of New York,` havo invented certain new and useful Improvements in ChangeableStencil-Plates; and I do hereby declare that',

1the following is a full and exact description thereof. f p

I will first describe whatrI consider to be the'best 'means of carrying out my invention, and will afterwards designate the points which I'believe to be new therein.

`The accompanying drawings form a part of. this specification.

Figurel represents the body or main plate, and Figure 2 represents. the same, with the stencil-strips properly mounted therein. Similar letters of reference indicate likelparts in all ig-ures.

A is a'plate, of brassor tber suitable material, which is provided with an aperture, a, in which the letters,

which are to be s'tencilled are presented on the strips B B B B. .These strips are formed of brass or other suitable material, land are suliciently thin to be Iiexible, and te allow of bending in the manner described..

The desired figures, letters, or other marks, which are to bestencilled, are put on the strips B B B B, so that, by shifting the stripsendwise, in the plate A, the marks will be presented at the opening a. l

So far as has been specifically described, my invention has, been before known; but the means by which the strips were mounted in the plate, in the previous ed'orts in this direction, were objectionable, for the reason, among others, that the strips were necessarily held with their edges asunder, and this increased the spaces between Vthe letters or figures to :tn-'inconvenient extent. There were', also, other evils attendant on the former arrangements, which my invention completely avoids, l

My strips, B B, with their edges in contact eachwitli its neighbor, form a smooth surface across which to rub the stencil-brush. Each strip is run under vthe stencil-plate A, immediately adjacent tothe hole a, and is lcd lip through a narrow slot in the plate a. These slots are peculiarly disposed. The slots D'and E are nearer the hole a than thc slots C and'F, and they alternate in position. Each strip is led down againl through the wide slots G H. It will 'be better understood' from theiigurestban from along written description. The effect of the entire structure is to holdthestrips B B in contact with each other, and thus to present an improved construction and arrangement of the stencil-strips B B at the `point where they are aixed, while providing a very strong and convenient construction ofthe whole, with a small. expense for material and Afor labor..

I do not claim an adjustable stencil-plate, having a hole a and strips B B, adapted to be .moved so as to present different vgures or letters therein, except when the strips are mounted as herein specified; but, having now fully described my invention, i 1

lWhat claim as new instencil-plates, and desire to sccurebyn Letters Patent, 'is as follows:

I claim the within-describedslots C D E F, arranged relatively to the opening a and the strips B, tho whole being adapted to form an adjustable stencilLplate, possessing Vthe advantages and characteristics herein set forth; I
